Patagonia is the end of the world — geographically, spiritually, and for many trekkers, philosophically. The Torres del Paine National Park in Chilean Patagonia contains some of the most dramatic mountain scenery on the planet: the granite towers (torres) that give the park its name, the massive Grey Glacier, the French Valley, and the almost-unbelievable珑山脊 of Los Cuernos. This guide covers the two main trekking options for 2026.
W Trek vs O Circuit: The Fundamental Choice
The W Trek (4-5 days) Named for the shape of the route on a map, the W Trek covers the park’s three main highlights: the Torres (the towers), the Valle del Francés (French Valley), and the Grey Glacier. It can be done independently or as part of an organized group, and it’s the most popular option.
The O Circuit (7-10 days) The full loop around the Torres del Paine massif, adding the less-visited back side of the park, the Sierra Grande ridge, and more distance from the main tourist infrastructure. The O Circuit is more remote, more demanding, and significantly more rewarding. It includes everything the W Trek sees plus 4-5 additional days of wilderness.
The difference in a sentence: The W Trek gives you the photos; the O Circuit gives you the experience.
The W Trek: Day by Day
Day 1: Puerto Natales → Park Entrance → Las Torres Take a bus from Puerto Natales to the park entrance (Cerro Paine), then a park shuttle to the Las Torres sector. The hike to the base of the Torres viewpoint is 2-3 hours each way on a well-maintained trail. The Torres are most dramatic at sunrise when they glow orange — but this requires starting before dawn.
Day 2: Hostería → Valle del Francés The French Valley is the highlight of the W Trek for many. From Hostería Paine Grande, a 3-4 hour detour leads into the valley, surrounded by hanging glaciers, granite peaks, and the constant rumble of ice falling. You need to be here at midday to see the glacier activity.
Day 3: Paine Grande → Grey Glacier A full day hiking to and from the Grey Glacier viewpoint, passing the stunning Lago Grey with its icebergs. The contrast between the blue-white glacier and the dark blue lake is extraordinary.
Day 4: Paine Grande → Puerto Natales Morning catamaran crossing from Paine Grande to Pudeto, then bus back to Puerto Natales.
Book W Trek campsites and refugios (mountain lodges) through the CONAF official booking system — they open booking on September 1st each year for the following season. By October, the most popular campsites (Las Torres, Paine Grande, Chileno) are sold out.
The O Circuit: Beyond the W
The O Circuit adds approximately 5 days to the W Trek, looping counterclockwise around the entire Torres del Paine massif. The extra sections include:
- The remote backcountry between Grey Glacier and the John Gardner Pass (the highest point on the circuit, 1,241m, with views of the Grey Glacier from above)
- The condor-filled Valle del Toro
- The eastern approach to the Torres from the backside, giving a completely different perspective
The O Circuit requires 8-10 days minimum because of the longer distances and the backcountry campsites that require longer daily stages. Independent hikers must carry all their food, cooking equipment, and shelter — the backcountry has fewer refugios.
Book O Circuit refugios and campsites through the same CONAF system as the W Trek, but do it immediately when bookings open — the backcountry sites have very limited capacity.
Getting to Torres del Paine
Puerto Natales is the gateway town to Torres del Paine, located approximately 1 hour from the park entrance. To reach Puerto Natales:
From Santiago: LATAM and Sky Airline operate daily flights from Santiago to Punta Arenas (PMC), the southernmost commercial airport in Chile. From Punta Arenas, it’s a 3-hour bus ride to Puerto Natales.
From Buenos Aires: Aerolíneas Argentinas operates direct flights from Buenos Aires (EZE) to Punta Arenas. This is sometimes cheaper than the Santiago route for travelers coming from Europe or North America.
Within Patagonia: Bus from El Calafate (Argentina) to Puerto Natales is about 5 hours. Alternatively, book a multi-day Patagonia tour that includes both Chilean and Argentine Patagonia.
Patagonia Trekking Gear
The weather in Torres del Paine is notoriously unpredictable — you can experience all four seasons in a single day. The famous Patagonian wind can exceed 100 km/h on exposed ridgelines.
Essential gear:
- Waterproof hardshell jacket (windproof is equally important)
- Quick-drying base layers (no cotton — if it gets wet you’ll freeze)
- Trekking poles (the winds on exposed sections are genuinely dangerous without them)
- Waterproof hiking boots (broken in before you arrive)
- Sleeping bag for refugios (not all provide blankets)
- Water bottle (tap water is safe throughout the park)
- Sunscreen (the UV index is extreme at southern latitudes)
Book Patagonia treks and guided tours through Klook — multi-day guided W Trek options include all accommodation, meals, park fees, and equipment, which significantly simplifies logistics for first-time visitors.
